This manual contains operation information for the Terahertz Technologies Inc. FTE-7000A Optical Time
Domain Reflectometer. This OTDR may be operated by using the touch scree or the onboard key pad. The
touch screen is a resistive style screen and only proper stylus devices should be used when operating the
OTDR using the touch screen capability.
This guide is written to instruct operation via the onboard keypad. There will be tips throughout the manual to
assist with touch screen operation.
Warning
A warning alerts to situations that could cause personal injury.
Caution
A caution alerts to situations that may cause damage to the equipment or produce poor testing condi-
tions resulting in inaccurate test results.
Note
A special annotation that will assist the user with operational features.
Chapter 1 Using This Manual
There are warnings, cautions and notes posted throughout this manual.
Optical time domain reflectometers are optical instruments that do emit laser radiation and though this level
of radiation is not considered a danger, there are safety considerations and certain practices that should be
followed.
Please read and follow all warning and caution information noted in this manual.
Precautions
Touch Screen Tip
These tips will be found throughout the manual to assist with touch screen operation.

FTE-7000A User's Guide Rev A 5/20142
This product has been designed and tested in accordance with the manufacturer’s safety standards, and has
been supplied in a safe condition.
This document contains information that must be followed by the user to ensure safe operation and to maintain
the product in a safe condition. Failure to follow these safety warnings and cautions can result in harm to the
user or damage to the instrument.
Warning
Personnel should always be aware when working with fiber optic test equipment that active fibers may
be present, therefore infrared optical energy may be present.
Warning
Never look directly into the end of a connected fiber optic cable or fiber optic interface of optical test
equipment, to do so could expose the user to laser radiation and could result in personal injury.
Warning
To Prevent Fire or Shock Hazard:
Chapter 3 of this manual is a quick start guide. Prior to using the quick start guide or operat-
ing the equipment in any way, it is highly suggested the user reads all safety information.
Chapter 2 Safety
Do not install battery types other than those specified by the manufacturer
Do not use the charger without the batteries installed
Do not expose the battery charger to rain or excessive moisture
Do not use the AC adapter when there are signs of damage to the enclosure or cord
Ensure the correct charger is being used for the local line voltage
Do not use any other charger than the one provided with this instrument.
The information in this chapter pertains to safety consideration of OTDRs in general.

3FTE-7000A User's Guide Rev A 5/2014
Failure to follow these cautions statements may void the warranty of, or cause damage
to this equipment.
Caution
Fiber-optic connectors are easily contaminated or damaged. The connection to the OTDR is physical
contact type of connections and dirty or damaged connectors may impair the instruments capabilities at
minimum and at worst result in the need to return the OTDR to the factory for expensive repairs. Prior
to making any connection to the unit, ensure that all proper cleaning procedures have been followed.
Use UPC Finish Connectors Only -- DO NOT insert APC connectors into the optical ports.
Caution
The OTDR is equipped with a protection circuit to avoid damage from live fiber connections The in-
strument will not operate properly with active fibers. Even with this protection, high power output from
EDFA’s or other equipment can damage detectors and should never be connected to the OTDR.
If a live fiber is connected to the OTDR and a scan is attempted, a warning dialog will be displayed as in
fig. 2.1. Immediately remove the live fiber from the OTDR and press select to continue testing.

Chapter 3 Quick Start Guide
Press to turn on the OTDR.
Use the directional buttons to highlight the OTDR icon and press to enter the OTDR function.
Connect the fiber to the appropriate port. (SM or MM OTDR Optical Port)
Press to enter the Menu mode. The menu is displayed at the top of the screen. (To hide the
menu, press the menu button a second time.)
Use the right button to highlight the (wavelength) icon and use to cycle to the desired wave-
length.
If approximate fiber length is unknown:
Press to have the OTDR start a test using the selected wavelength with the OTDR determining
the most appropriate range and pulse width. (Autotest will set the averaging time to 60sec.)
If approximate fiber length is known:
Set the Wavelength as above and further set the range, pulse width and averaging time.
Press to open the icon menu, use the left or right arrow to highlight the (range) and use
to cycle through the available ranges of 250m, 1km, 4km, 16km, 64km, 128km or 256km.

available pulse widths of 5ns, 10ns, 30ns, 100ns, 300ns, 1us, 3us, 10us or 20us. (Not all pulse
widths will be available, only pulse widths appropriate for the selected range will be presented)
Press the left or right button to highlight the (average) icon and use to cycle to the averaging
times of Real-Time, 15 seconds, 1, 4, 16 or 40 minutes.
Press to exit the menu mode and hide the menu bar.

6.3 Power Requirements
The FTE-7000A is equipped with a 100-240V-0.3A input and 9V, 0.67A center positive output universal AC/
DC battery charger. This charger is supplied with interchangeable mains for US, Great Britain, Europe and
Australia The unit is shipped with 4-AA NiMH batteries (2700mA hours). Fully charged battery pack will
typically enable approximately 4 of use. Fully discharged batteries require 6 - 8 hours of recharging.

FTE-7000A User's Guide Rev A 5/201410
Warning
To Prevent Fire or Shock Hazard:
Do not install battery types other than those specified by the manufacturer
Do not use the charger without the proper NiMH batteries installed
Do not expose the battery charger to rain or excessive moisture
Do not use the AC adapter when there are signs of damage to the enclosure or cord
Ensure that you are using the correct charger for the local line voltage
Do not use any other charger than the one provided with this instrument.
Failure to follow these caution statements could cause unsafe conditions for the operator and
equipment and may void the warranty.
6.4 Battery Replacement
To replace the batteries, remove the OTDR from the protective boot by pulling the bottom of the boot down
and back allowing the bottom of the unit to be lift out. The battery door is located on the back side of the
unit. Replace the batteries with only high quality AA NiMH batteries. Spare battery packs are available with
a charging unit for extended battery operation. If you install NiMH batteries that are dead or less than 1 volt
each, charge these batteries for one (1) hour before using the OTDR. For proper maintenance, batteries require
a monthly recharge.

Chapter 7 OTDR Operation
7.1 Key Pad
Power button, turns the unit On and Off. (Hold for 1 second)
Scan button starts a scan or stops scan.
AutoTest button operates range finder trace mode. The Range Finder mode momentarily checks test conditions
and starts a scan at the wavelength selected by the user but allows the OTDR to determine the pulse width and
range parameters.
The Menu button displays and hides the icon menu at the top of the display. It will also back out of most menu
selected screens. In the project folder and file manager it opens the file/edit menu bar. When the menu is
displayed at the top of the screen, the focus of the LRUD buttons and the select buttons are on the icon menu
and no longer on the trace cursors.
Toggles between A and B as the active cursors.
Selects the Zoom level, each press increments through the levels of 1x, 2x, 4x, 8x, 16x and 32x.
In the menu mode, the select button actuates highlighted item.
While in the trace mode the directional buttons are used to move the cursors. In the Menu mode, the Left and
right buttons move between the icons. The up button hides the menu bar or moves cursor up in drop-down
menus and the down button opens drop-down menus or move cursor down while in a drop-down menu.
